Subgroup ($H$) information

Description:$C_6\wr C_2$
Order: \(72\)\(\medspace = 2^{3} \cdot 3^{2} \)
Index: \(9\)\(\medspace = 3^{2} \)
Exponent: \(12\)\(\medspace = 2^{2} \cdot 3 \)
Generators: $a, d^{2}, c^{3}, c^{2}, d^{3}$ Copy content Toggle raw display
Derived length: $2$

The subgroup is nonabelian, supersolvable (hence solvable and monomial), and metabelian.

Ambient group ($G$) information

Description: $C_6^2:D_9$
Order: \(648\)\(\medspace = 2^{3} \cdot 3^{4} \)
Exponent: \(36\)\(\medspace = 2^{2} \cdot 3^{2} \)
Derived length:$3$

The ambient group is nonabelian and monomial (hence solvable).

Automorphism information

While the subgroup $H$ is not characteristic, the stabilizer $S$ of $H$ in the automorphism group $\operatorname{Aut}(G)$ of the ambient group acts on $H$, yielding a homomorphism $\operatorname{res} : S \to \operatorname{Aut}(H)$. The image of $\operatorname{res}$ on the inner automorphisms $\operatorname{Inn}(G) \cap S$ is the Weyl group $W = N_G(H) / Z_G(H)$.

$\operatorname{Aut}(G)$$C_3^4.(S_3\times S_4)$, of order \(11664\)\(\medspace = 2^{4} \cdot 3^{6} \)
$\operatorname{Aut}(H)$ $C_2^2\times D_6$, of order \(48\)\(\medspace = 2^{4} \cdot 3 \)
$\operatorname{res}(S)$$C_2\times D_6$, of order \(24\)\(\medspace = 2^{3} \cdot 3 \)
$\card{\operatorname{ker}(\operatorname{res})}$\(18\)\(\medspace = 2 \cdot 3^{2} \)
$W$$D_6$, of order \(12\)\(\medspace = 2^{2} \cdot 3 \)
